“…Several soil samples with the reported aqua regia Tl value from the WEPAL International Soil Exchange Programme were analyzed for the comparison of the results. For all tested samples the results achieved were in the very good agreement with the reported results [12].…”

“…There is little detailed information on the Tl status of soils [8,9,10,11,12,13,14]. A median of 0.29 mg kg -1 and a maximum of more than 50 mg kg -1 were found for French soils [8,9], and a median value of 0.25 mg kg -1 and a maximum value of 2.83 mg kg -1 were found for more than 450 tested soil samples in the Czech Republic.…”

“…Tl and its compounds are non-essential, and they are toxic to all organisms. Demand for determination of Tl, especially in countries where soils derived from melanocratic granites occur, is expected to rise because Tl in soils is mostly of pedogeochemical origin [7,8,9,10,11,12].…”

The relationship between aqua regia (ISO 11466) and HNO(3)-H(2)O(2) (ISO/CD 20279) extraction procedures for atomic emission spectrometric (ICP/OES and ICP/MS) determinations of Tl, P, Mn, Fe, Mg, Ca, Sr, Al, K, As, Bi, Zn, Pb, Co, Cd, Ni, V, Be, Cu and Cr was investigated. Soil samples (155) representing areas with different contents of the elements were selected for the comparison. Tl was the element of the highest interest and therefore the sampling sites were chosen to achieve as wide range of Tl contents as possible. Both extraction procedures are comparable in results (differences lower than 10% for the most of the elements) for all the tested elements. Statistically non-significant differences between the two extraction procedures were found for P, Zn, V and K (the slope was very close to 1 and the intercept included zero). Statistically significant values of intercepts were found for Fe, Al, Ca, Cd, Sr and Ni. Significantly higher results for aqua regia were found for Cu (12%), Pb (17%), Mn (11%) and lower results by aqua regia were found for Mg (4%), As (13%), Co (20%), Be (11%), Cr (4%) and Bi (6%). The results for Tl, the element of the highest interest, after HNO(3)-H(2)O(2) extraction procedure, were approximately 6% higher than the results after aqua regia extraction. Content of Tl in the soil samples was from 0.08 to 2.8 mg kg(-1). A highly significant linear relationship was found (R(2)=0.97).

“…Plant samples were cleaned immediately after the harvest by a quick washing with deionized water to remove dust particles, dried at laboratory temperature and finely ground. The samples (1 g) were digested by nitric acid (8 ml HNO 3 and 10 ml H 2 O) in microwave digestion system at 145°C and 700 W for 5 min, 180°C and 600 W for another 5 min and finally at 180°C and 1000 W for the next 5 min (Medek et al 2001). The digests were adjusted to the final volume of 50 ml with deionized water.…”

A pot experiment focused on the study of factors influencing thallium transfer from contaminated soils into kale (green cabbage, Brassica oleracea L. var. acephala, variety Winterbor F1) was evaluated. Three different types of topsoils with naturally low content of thallium (heavy, medium and medium-light soil) were used for pot experiments. The soils were contaminated with thallium sulfate to achieve five levels of contamination (0, 0.52, 2.10, 4.20 and 5.88 mg/kg). There were six replicates for each combination (90 pots in the experiment). The first part of the experiment started in the year of contamination (2001) and continued in 2003. The soil samples and the samples of kale (leaves and stalks were sampled separately) were collected and analysed. Kale was found to be able to accumulate Tl without any influence on yield. The highest thallium concentration was found in the leaves of kale in the first year of the experiment and reached 326 mg/kg dry matter. Bioaccumulation factor (Biological Absorption Coefficient -BAC) was found to be over 80 during the first year of the experiment. In the third year the BAC was around 3 for the soil with the highest pH and the highest organic matter content but as high as 15 for an acid soil with the lowest content of organic matter and the lowest Cation Exchange Capacity (CEC) of soils. The content of thallium in the leaves of kale was found to be 7 to 10 times higher than in the stalks in the third year. In the first year this ratio was up to 18. From these findings it can be concluded that the ability of some plants of Brassicacea family, that are planted as common vegetables, to accumulate thallium is very high and can be a serious danger for food chains. Neutral soils high in CEC and organic matter are able to bind thallium more effectively than poor acid soils and the transfer of Tl into plants from these soils is substantially lower. The uptake of Tl from contaminated soils into kale can be very high and without any negative effect on the plant growth. The transfer of Tl into kale decreases with the time necessary to reach the equilibrium between the added Tl and the soil (ageing of a sample).

“…16 Though the methods containing these reagents are sensitive, lack selectivity and suffer from serious interference of foreign ions, which normally occurs in the determination of thallium(III). Other considerable methods used for the determination of thallium include, ICP-MS, 17,18 AAS, 19,20 potentiometry, 21 and voltammetry. 22 Most of these methods are disadvantageous in terms of cost and instruments used in routine analysis.…”
